Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a garbage processing device.

(Prior Art) Conventionally, for example, in high-rise buildings, food manufacturing plants, large-scale housing complexes, etc., garbage processing equipment has been installed to hygienically dispose of large amounts of garbage. Generally, this garbage processing device has a garbage storage/discharge section that temporarily stores the garbage and discharges the garbage to the outside (for example, a garbage collection vehicle) when the storage amount reaches a certain amount, and a garbage storage/discharge section that introduces the garbage into the garbage storage/discharge section. It is equipped with a dust shoot.

As a matter of course, such a garbage processing apparatus becomes contaminated with dust adhering to the inner wall of the apparatus as time passes, and therefore it is necessary to remove the dust adhering to the inner wall of the apparatus. Particularly in facilities, such as food manufacturing factories, where strict regulations are imposed on odors in terms of hygiene management, it is necessary to remove the dust adhering to the inner walls of the equipment before it rots and begins to emit odors. Frequent cleaning of the inner wall of the dust chute is especially effective for this purpose.

(Problem to be solved by the invention) However, when garbage is stored in the garbage storage and discharge section, there is an inconvenience that not only the inside of the garbage storage and discharge section cannot be cleaned but also the inner wall of the dust chute cannot be cleaned. . The reason for this is that the sealing properties of the outlet of the dust storage and discharge part are sufficient for dust but not for water, and as a result, sewage from cleaning the inner wall of the dust chute leaks from the outlet. This is unfavorable from a sanitary standpoint, and if the waste water is contained in the waste, there is a problem that the waste water may be scattered on the road surface during transportation by a waste collection vehicle.

Therefore, since garbage is stored in the garbage storage and discharge section for a relatively long period of time, conventional garbage processing equipment cannot actually perform the above-mentioned cleaning satisfactorily, and sanitary conditions are not maintained. There were management issues.

Here, as a device for cleaning the inner wall of a dust chute, there is a device shown in Japanese Patent Publication No. 52-48760, which closes the chute with a bottom plate provided in the chute so that it can be opened and closed. In terms of sex, it is insufficient for water,
The above-mentioned problems were previously unresolved.

(Means for Solving the Problems) The garbage processing device of the present invention is a garbage disposal device that is equipped with a garbage storage and discharge section that temporarily stores garbage and discharges it to the outside, and a dust chute that introduces garbage into this garbage storage and discharge section. In the processing device, a cleaning shutter is provided at the bottom of the dust chute, and is provided diagonally downward and retractable into the dust chute, and is capable of completely blocking the dust chute. A sewage outlet is provided on the side of the dust chute facing the tip of the shutter to wash the dust chute and discharge the washing water that flows down to the washing shutter to the outside of the dust chute, and the sewage outlet has an opening/closing lid. The opening/closing lid is always urged in the closing direction by the urging member, and when the cleaning shutter blocks the dust chute, the tip of the cleaning shutter presses the opening/closing lid against the urging force of the urging member. It is designed to open, and a watertight material is interposed between the cleaning shutter and the dust chute,
This watertight material prevents the cleaning water for cleaning the dust chute from leaking below the cleaning shutter.

(Function) When cleaning the inner wall of the dust chute while dust is stored in the dust storage and discharge section, the cleaning shutter provided at the bottom of the dust chute is closed to shut off the dust chute. This prevents sewage during cleaning from flowing into the dust storage/discharge section, and the sewage is discharged from the top surface of the cleaning shutter to the outside of the dust chute via the sewage discharge port provided on the lower side wall of the dust chute. In addition, if the inside of the dust storage and discharge section is empty, open the cleaning shutter and open the dust chute. As a result, cleaning water is introduced from the dust chute into the dust storage and discharge section, and both are cleaned at the same time.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a state in which a garbage processing apparatus according to the present invention is installed in a building such as a factory.

This garbage processing device includes a garbage storage and discharge section 1, a dust chute 2 that introduces garbage into the garbage storage and discharge section 1, a hopper 3 attached to the top of the dust chute 2, and a hopper 3 installed on the side of the hopper 3. and a reversing input section 5 for reversing the garbage transport container 4 and throwing the garbage therein into the hopper 3,
In the case of this embodiment, the garbage storage and discharge section 1 is installed on the lowest floor of the building, and the hopper 3 and the reversing input section 5 are installed on the upper floor.

The garbage storage and discharge section 1 is, for example, a horizontally installed cylindrical drum 6, and this drum 6 is connected to two pairs of drums on a base 8 via rings 7, 7 attached at two places on its outer circumferential surface. It is rotatably supported by rollers 9, 9, . Further, a spiral blade 14 is attached to the inner wall of the drum 6 along the wall surface, and the spiral blade 14 pushes the internal garbage toward the discharge port 13 by its rotation.
The discharge port 13 is configured to be opened and closed by a lid 15, which is pivotally mounted on a frame 16 erected on the base 8 so as to surround the discharge port 13, and when the drum 6 rotates. closes the discharge port 13 while rubbing against its periphery. The code 17 in the figure is
An opening/closing cylinder for opening and closing the lid 15 is attached to the frame 16. Further, the garbage discharged from the drum 6 is placed below the discharge port 13.
For example, a belt conveyor 1 that is sent to a garbage collection vehicle, etc.
8, and a guide plate 19 for preventing dust from falling is provided around the belt conveyor 18 except for the tip end on the delivery side. Incidentally, the dust storage and discharge section 1 is a drum 6 as described above.
It is not limited to.

The dust chute 2 is a cylindrical body with a square cross section, and its lower end is connected to a communication pipe 20 connected to the inlet of the drum 6, while the hopper 3 is attached to its upper end. At the lower end of the dust chute 2, a cleaning shutter 21 is provided which faces obliquely downward and is movable into and out of the dust chute 2.

As shown in FIG. 2, this cleaning shutter 21 is slidably supported on a pedestal 22 provided on the outer wall of the dust chute 2, and is slid by a shutter drive motor 23 installed on the pedestal 22. .
As shown in FIG. 3, the driving force of this shutter drive motor 23 is generated by two motors attached to the back side of the cleaning shutter 21 near both side edges along the direction of movement.
Book racks 24, 24 and shutter drive motor 2
Pinion gear 2 attached to shaft 25 of 3
6 and 26. In addition, as shown in FIG. 3, on both side edges of the cleaning shutter 21,
Guide parts 27, 27 having a square cross section are provided over the entire length, and guide grooves 28, 28 for guiding these guide parts 27, 27 are formed in the side wall of the dust chute 2. A watertight material 29 made of, for example, rubber is attached to the inner wall surface of these guide grooves 28, 28 so as to rub against the circumferential surface of the guide portions 27, 27 of the cleaning shutter 21, and these watertight materials 29... ... prevents dirty water during cleaning from leaking into the drum 6 from the gaps between the guide portions 27, 27 and the guide grooves 28, 28. Note that the guide portions 27, 27 and the guide grooves 28,
The shape of 28 is not limited to the illustrated example. In addition, droops 30, 30 are suspended from the upper edges of the open sides of the guide grooves 28, 28, respectively, so that sewage does not flow into the guide grooves 28, 28 when cleaning the inner walls of the dust chute 2, or when garbage is thrown in. This prevents them from entering the guide grooves 28, 28.

Further, a side wall of the dust chute 2 that comes into contact with the tip of the cleaning shutter 21 is provided with a dust chute 2.
A sewage discharge port 31 is provided for discharging sewage from washing the inner walls of the dust chute 2 to the outside of the dust chute 2, and an opening/closing lid 32 is attached to the sewage discharge port 31 so as to be openable and closable. This opening/closing lid 32 is always biased in the direction of closing the waste water outlet 31 by a spring 33, so that the cleaning shutter 21 closes the dust outlet 2.
Only when the cleaning shutter 21 enters the interior, it is pushed by the upper edges of the guide portions 27, 27 of the cleaning shutter 21 and rotated upward against the elastic force of the spring 33, thereby opening the wastewater discharge port 31.

Note that the opening and closing operations of the cleaning shutter 21 are not limited to those described above; for example, the cleaning shutter may be pivotally mounted within the dust chute 2 and opened and closed by rotational movement.

A water collector 34 is provided near the outside of the waste water outlet 31 to receive the waste water discharged from the waste water outlet 31. The water is discharged to a drainage ditch (not shown) through the connected drainage pipe 35.

Further, the upper peripheral wall of the dust chute 2 is provided with a plurality of water spray nozzles 36 that spray cleaning water toward the inner wall thereof. Note that the water spray nozzles 36 do not necessarily have to be provided, and for example, a hose having a water spray nozzle at its tip may be introduced into the dust chute 2 through the hopper 3 during cleaning.

In the reversing charging section 5, the rotational force of the garbage transporting container 4 is small during reversing charging, and the mouth edge of the trash transporting container 4 is positioned above the hopper 3 during reversing charging. For example, a device equipped with a link mechanism as disclosed in Japanese Utility Model Publication No. 43-265583 is preferably used.

Next, a cleaning procedure for such a garbage processing apparatus will be explained.

When cleaning the inner wall of the dust chute 2 while dust is stored in the drum 6, the shutter drive motor 23 is first started to move the cleaning shutter 21 into the dust chute 2, and the dust chute 2 is shut off. At this time, the opening/closing lid 32 is pushed open by the cleaning shutter 21 as described above, and the waste water outlet 31 is opened. Then, cleaning water is sprayed from the water spray nozzle 36 to wash off the dust adhering to the inner wall of the dust chute 2. This wastewater containing dust flows down onto the cleaning shutter 21 and is discharged from the wastewater outlet 31 to the water collector 34.
It is discharged to the drain through the drain pipe 35. When cleaning is completed, the shutter drive motor 23 is reversed to move the cleaning shutter 21 out of the dust chute 2, and the dust chute 2 is opened.

In addition, when there is no dust inside the drum 6, when cleaning the inner wall of the dust chute 2 and the inside of the drum 6, the opening/closing cylinder 17 is operated to open the lid 15 that closes the discharge port 13 of the drum 6. 13 and the drum drive motor 12
is activated to rotate the drum 6. In this state, with the dust chute 2 open, open the water nozzle 36.
...Spray more cleaning water. At this time, the cleaning water flowing into the drum 6 via the dust chute 2 is sent to the discharge port 13 side by the spiral blade 14 on the inner wall, passes over the belt conveyor 18 from the discharge port 13, and is provided below the tip of the belt conveyor 18. and is discharged into a drainage ditch (not shown).

(Effects of the Invention) As described above, according to the garbage processing device of the present invention, when cleaning the dust chute, the cleaning shutter protrudes into the dust chute to completely shut off the dust chute, and the cleaning shutter A watertight material is interposed between the dust chute and the dust chute so that the cleaning water that cleans the dust chute does not leak below the cleaning shutter, so that even when dirt is stored in the dust storage and discharge section, it can still flow into the dust storage and discharge section. By blocking the inflow of cleaning water, only the inner wall of the dust chute can be cleaned. Moreover, since the cleaning water that has flowed down into the dust chute is discharged from the waste water outlet, the dust chute can be cleaned with a large amount of cleaning water, and dirt within the dust chute can be reliably removed.

In addition, when the cleaning shutter shuts off the dust chute, the opening/closing lid that opens and closes the waste water outlet is pressed outward against the urging force of the urging member by the tip of the cleaning shutter, so that the cleaning The structure is simple as there is no need for any member to open the lid in conjunction with the shutoff of the dust chute by the cleaning shutter, and the lid opens only when the cleaning shutter shuts off the dust chute. Leaking odors can be minimized. Therefore, it can be used satisfactorily even in facilities that are subject to strict hygiene control regulations.
